The clarification came after Claudio Sulser, the disciplinary chief of world football's governing body, had said on Thursday: "No, you can't limit those rights to the player because it would be disproportionate."

But the spokeswoman told Press Association Sport: "He is not allowed to participate in any football activity during the ban period, and as such is also not allowed to train with the team during the ban."

Sulser had confirmed that Suarez, 27, was free to join Barcelona while serving his ban for biting Italy's Giorgi Chiellini -- the third biting ban of his career.

Liverpool remain in talks with Barca over Suarez, and Sulser told a news conference: "The player cannot have any activity related to football, but a medical examination for a transfer, yes -- the sanction is not linked to transfer rights.''

He said: "It's a sanction against the player. That is the risk if you are a player and you are sanctioned at the World Cup. I agree with you it's a problem for Liverpool, but the sanction is in the disciplinary regulations."
